RF7170D Dual-Band EGSM900/DCS1800 Transmit Module
The RF7170D is a dual-band (EGSM900/DCS1800) GSM/GPRS Class-12-compliant transmit module with two symmetrical receive ports. This transmit module builds upon RFMD's leading power amplifier with PowerStar® integrated power control technology, pHEMT switch technology, and integrated transmit filtering for best-in-class harmonic performance. The results are high performance, reduced solution size, and ease of implementation. The device is designed for use as the final portion of the transmitter section in an EGSM900/DCS1800 handset and eliminates the need for a PA-to-antenna switch module matching network. The device provides 50 Ohm matched input and output ports requiring no external matching components. The RF7170D features RFMD's latest integrated power-flattening circuit, which significantly reduces current and power variation into load mismatch. Additionally, a VBATT-tracking feature is incorporated to maintain switching performance as supply voltage decreases. The RF7170D also integrates an ESD filter to provide excellent ESD protection at the antenna port. The RF7170D is designed to provide maximum efficiency at rated POUT.
